I did care to a degree until my iPad was an innocent victim after a particularly upsetting Call of Duty session. I had it sitting next to me on the couch, and slammed my hand down on the cushion after I got killed by someone proneing in the grass for the 50th time that game. Next thing I know, my hand really, really, hurts.
The damage to the iPad was minor -- the volume control area of the outside frame is a bit bent. You can't tell unless you're looking for it though.
Looking forward to buying my iPad 3 and getting a do-over on keeping it perfect.
